IMPROVEMENT IN WINDMILLS.

Specification forming part of Letters Patent N 0. 182,394, dated September 19, 1876; application filed May 16, 1876.

To all whom it may concern:

Be it known` that I, EDWARD WILLIAMS, of Potosi, in the county of Grant and State of Wisconsin, have invented a new and InI- proved Windmill, of which the following is a specification The invention consists of a solid wheel of sheet metal, the vanes of which are of concave form in cross-section, and there is a secondary set of curved vanes outside of the rims to increase the capacity of the wheel. The power is transmitted `to the pump-rod by a pair of eccentric-wheels, and a lever giving increased leverage on the upstroke, with quicker motion on the downstroke, and enabling the wheel to lift from a greater depth. The tail-vane is double, and diverges each way, so that the wind has greater power to hold it steady. The connecting-rod worksl upward from the crank to a lever, having the pumprod connected to it in such manner that the pump-rod has but little vibration in the hollow axis of the turn-table, and thus does not require so much space as when the crank works over hollow axes. rIhe main stern is set'in an adjustable step, for plumbing the turn-table readily when the tower settles.

Figure l is a top view of my improved windmill; and Fig. 2 is a section on line a: x.

Similar letters of reference indicate corresponding. parts.

The wheel is constructed of two wroughtiron bands, A B, tted on the arms G radiating from the'hulo D, concave metal vanes E, and the short concave vanes F, attached to the outside of the outer band B. Instead of making the crank on the wheel-shaft G, there is a counter crank-shaft, H, turned by the eccentric-wheels I, to give a slow and powerful upstroke and quick downstrokaand the crank-shaft is coupled to the lever J by connecting-rod K, so that the pump-rod L, which is connected to the lever, is not subject to the vibrations of the crank. The wheel is held in the wind by the weighted cord M, suspended from a pulley on tail-vane O, and pulling the table P by the pulley Q. R is a cord for stopping the wheel byhand. It is connected to the tail-vane, and passes around pulleysS and I and down the hollow axis. 'Ihe table which supports the wheel is mounted on the inner I stem U, which turns in the outer stem V, on which the tail-vane O is mounted. The stem V rests in the adjustable oil-box W, by which the wheel can be righted readily when -the tower settles. X represents the laterally-diverging plates of the tail-vane, to enable the wind to have better effect and hold it steadier.

Having thus described niy invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination, in a windmill, ot' the crank-shaft for working the pump-.rodand eccentric gears connecting said crank-shaft with the wheel-shaft, substantially 'as specied.

2. The combination, in a windmill, of a lever, J, having the pump-rod L connected to it, and a crank-shaft connected with said lever and located to one side of the hollow axis in which the pump-rod works, substantially as specified.
